Natural Product Identification

Common Name

4-[(acetyloxy)methyl]-6-[(3-methylbutanoyl)oxy]-6,7a-dihydro-1h-spiro[cyclopenta[c]pyran-7,2'-oxiran]-1-yl 3-methylbut-2-enoate

Description

4-[(Acetyloxy)methyl]-6-[(3-methylbutanoyl)oxy]-6,7a-dihydro-1H-spiro[cyclopenta[c]pyran-7,2'-oxirane]-1-yl 3-methylbut-2-enoate belongs to the class of organic compounds known as iridoids and derivatives. These are monoterpenes containing a skeleton structurally characterized by the presence of a cylopentane fused to a pyran ( forming a 4,7-dimethylcyclopenta[c]pyran), or a derivative where the pentane moiety is open. 4-[(acetyloxy)methyl]-6-[(3-methylbutanoyl)oxy]-6,7a-dihydro-1h-spiro[cyclopenta[c]pyran-7,2'-oxiran]-1-yl 3-methylbut-2-enoate is found in Valeriana officinalis and Valeriana sorbifolia. 4-[(Acetyloxy)methyl]-6-[(3-methylbutanoyl)oxy]-6,7a-dihydro-1H-spiro[cyclopenta[c]pyran-7,2'-oxirane]-1-yl 3-methylbut-2-enoate is an extremely weak basic (essentially neutral) compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as iridoids and derivatives. These are monoterpenes containing a skeleton structurally characterized by the presence of a cylopentane fused to a pyran ( forming a 4,7-dimethylcyclopenta[c]pyran), or a derivative where the pentane moiety is open.
